The MX-System series | # 8: The relay modules
The MRxxxx series relay modules allow the direct switching of high power levels and can also be used in a variety of ways. The MR3107-2001-2245 relay module is used to connect an ohmic or inductive 3-phase AC load. The integrated reversing contactor connection allows a 3-phase asynchronous motor to be operated in both directions of rotation.
The three phases, PE as well as temperature contacts and switchable 24 V DC contacts are led out on a hybrid B23 connector. This means that in addition to controlling a motor, the brake control and temperature measurement of the motor windings can also be realized via RTDs. The current carrying capacity per phase is 7 A.
